Abstract: In apparatus and a method for cooling a gas turbine blade (14), coolant in a liquid state, such as water, flows from a blade root portion toward an outer blade end portion under centrifugal force through one or more liquid coolant passages (17) travelling longitudinally within the blade (14), and such liquid flow coolant is introduced through a channel (18) to one or more nozzle (20) for converting the liquid flow to a mist. The mist flows from the outer blade end portion toward the blade root portion through one or more mist-flow coolant passages (19) and, having absorbed heat includes mist and gaseous vapor, is discharged from the blade into the motive fluid.

Abstract: in shadow mask colour cathode-ray tube, the mask (1) is provided with rows of slots (2, 2') extending from side to side of the mask and a line raster is constrained so that the raster are collinear with the slits. Open loop control may be used to achieve collinearity but closed loop control is preferred. Beam position signals may be derived from the mask by sensing secondary emission from different phosphors on the mask or by sensing currents generated in the mask. In the preferred embodiment the beams are dithered as they traverse the raster and the difference in the currents generated by a beam at the mask and at the conductive layer at the screen is detected. The first fundamental of the difference current indicates by its amplitude and phase the amount and direction of the misregistration of a beam and a slit. Different beams are distinguished by frequency multiplexing.
